Millibar to mmHg Converter
Pressure · unit-converter
Convert Millibar to mmHg with a fixed input and output unit, step-by-step formula line, and reference tables. All calculations bridge through pascal with fixed definitions (standard atmosphere = 101,325 Pa; torr and mmHg = atm/760; plus industrial/manometer units like kgf/cm², inHg, inH2O, and mmH2O).
About Millibar
Millibar (mbar) equals 100 Pa and is numerically identical to hPa. It appears in weather and legacy instrument labels.
About mmHg
Millimeters of mercury (mmHg) is common in medicine (e.g. blood pressure). Here it uses the same Pa per unit as torr (133.32236842105263 Pa).
How to convert millibar (mbar) to millimeter of mercury (mmhg)
1 millibar equals 0.7500616827041697 mmhg in this tool (via pascal):
1 mbar = (100 Pa ÷ 133.32236842105263 Pa) mmhg = 0.7500616827041697 mmhg
Each millibar carries 100 Pa and each mmhg 133.32236842105263 Pa, so one mbar equals 100 ÷ 133.32236842105263 mmhg.
Let p(mbar) be pressure in Millibar (mbar), and p(mmhg) in mmHg (mmhg). Then:
p(mmhg) = p(mbar) × (100 / 133.32236842105263)
Equivalently, divide by how many mbar fit into one mmhg (Pa per mmhg divided by Pa per mbar):
p(mmhg) = p(mbar) ÷ 1.3332236842105263
Examples
Example #1: Convert 1 mbar to mmhg
1 mbar = 1 mbar × (100/133.32236842105263) mmhg = 0.7500616827 mmhg
1 mbar = 1 mbar ÷ 1.3332236842105263 = 0.7500616827 mmhg
1 mbar × (100/133.32236842105263) = 0.750062 mmhg
Example #2: Convert 10 mbar to mmhg
10 mbar = 10 mbar × (100/133.32236842105263) mmhg = 7.500616827 mmhg
10 mbar = 10 mbar ÷ 1.3332236842105263 = 7.500616827 mmhg
10 mbar × (100/133.32236842105263) = 7.500617 mmhg
Summary
To convert Millibar to mmHg, multiply the value in mbar by (100 Pa per mbar) / (133.32236842105263 Pa per mmhg). Equivalently: value_mmhg = value_mbar × (100 / 133.32236842105263). Numerically, 1 mbar equals 0.7500616827041697 mmhg.
Relationship context
Both Millibar and mmHg are converted by fixed multiples of the pascal. Multiplying by (Pa per mbar) ÷ (Pa per mmhg) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
